Description

Technical Field

[0001] This utility model relates to the field of plug-in frame technology, and in particular to a drawer-type functional unit plug-in frame for power distribution cabinets. Background Technology

[0002] In large industrial plants such as automobile manufacturing and machining, a stable power supply is required for various production equipment such as machine tools and automated production lines. Drawer-type functional unit plug-in frames can be flexibly configured with electrical components such as circuit breakers and contactors of different specifications according to the power requirements of different equipment, making it convenient to control and protect each piece of equipment individually.

[0003] In the existing technology, some power distribution cabinets use guide rails and plug-in interfaces to facilitate convenient operation of drawer-type functional unit plug-in frames. High-precision guide rails are provided on both sides of the frame. The drawer-type functional units are smoothly pushed in and pulled out along the guide rails by pulleys or sliders. When inserted, the plug-in interface on the unit accurately aligns with the fixed contacts in the frame to establish an electrical connection and realize the transmission and distribution of electrical energy.

[0004] However, in actual use, electronic components produced by different manufacturers have differences in size, shape and interface specifications. If the plug-in frame cannot be installed adaptively, the staff will need to spend a lot of time finding the matching installation position and method. In some cases, the components may not be able to be installed due to incompatibility with the frame, which will cause work to stop and prolong the installation and commissioning cycle of the power distribution cabinet. In response to the above problems, a drawer-type functional unit plug-in frame for power distribution cabinets is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a drawer-type functional unit plug-in frame for power distribution cabinets, which aims to improve the problem that some electronic components cannot be self-adaptively installed in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The drawer-type functional unit plug-in frame of the power distribution cabinet includes a mounting frame. Mounting blocks are fixedly connected to the front and rear sides of the mounting frame. A connecting plate is fixedly connected to the adjacent side of the two mounting blocks. An adaptive mounting mechanism is fixedly connected to the outside of the connecting plate. An adjustment position mechanism is fixedly connected to the outside of the mounting frame.

[0008] The adaptive mounting mechanism includes a mounting housing, which is fixedly connected to the outside of the connecting plate. A return spring is fixedly connected inside the mounting housing. A pressing rod is slidably connected to the outside of the mounting housing. A mounting clamp is fixedly connected to the outside of the pressing rod. Connecting frames are fixedly connected to both the upper and lower ends of the pressing rod. A rotating plate is rotatably connected to the outside of the connecting frame. A connecting frame is rotatably connected to the outside of the rotating plate. A damping block is fixedly connected to the bottom of the connecting frame. A reset assembly is fixedly connected to the outside of the connecting plate.

[0009] As a further description of the above technical solution:

[0010] The reset assembly includes a fixing rod, which is fixedly connected to the outside of the connecting plate, and a tension spring is sleeved on the outside of the fixing rod.

[0011] As a further description of the above technical solution:

[0012] The position adjustment mechanism includes an adjustment housing, the outside of which is slidably connected to the inside of the mounting frame, and the inside of which is slidably connected to a limit plate.

[0013] As a further description of the above technical solution:

[0014] Mounting brackets are fixedly connected to the left and right sides of the outer side of the adjusting housing. A connecting shaft is fixedly connected to the outside of the mounting bracket. A rotating plate is rotatably connected to the outside of the connecting shaft. A positioning rod is fixedly connected to the outside of the rotating plate.

[0015] As a further description of the above technical solution:

[0016] A telescopic rod is fixedly connected to the outside of the rotating plate, and a mounting spring is sleeved on the outside of the telescopic rod;

[0017] As a further description of the above technical solution:

[0018] The mounting frame has multiple slots on its exterior, and the exterior of the positioning rod engages with the interior of the slots.

[0019] As a further description of the above technical solution:

[0020] The outer side of the rotating plate is in contact with the outer side of the mounting clamp, and the outer side of the mounting clamp is in contact with the outer side of the mounting housing;

[0021] As a further description of the above technical solution:

[0022] One end of the tension spring is fixedly connected to the inside of the connecting plate, and the other end of the tension spring is fixedly connected to the outside of the damping block.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the mounting clamp can then press the extrusion rod, causing the rotating plate outside the extrusion rod to rotate. Under the action of the rotating plate, the rotating plate drives the damping block to slide outside the connecting plate through the connecting frame. This allows the damping block to press the tension spring outside the fixing rod, thereby fixing the electronic component with the mounting clamp and pressing the reset spring with the extrusion rod, thus improving the installation stability of the electronic component.

[0025] 2. In this utility model, by pressing the rotating plate, the rotating plate compresses the mounting spring outside the telescopic rod, which in turn causes the rotating plate to separate from the slot outside the mounting frame through the positioning rod. This allows the mounting frame to slide inside the adjusting housing. When the mounting frame is adjusted to the appropriate position, the rotating plate is released, causing the mounting spring to rebound and the rotating plate to separate from the slot through the positioning rod, thus achieving the adjustment of the mounting frame.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a drawer-type functional unit plug-in frame for a power distribution cabinet, including a mounting frame 1. The mounting frame 1 has a rectangular frame structure, and its external dimensions are designed according to the specific specifications of the power distribution cabinet and the dimensions of the drawer-type functional unit. Mounting blocks 2 are fixedly connected to both the front and rear sides of the mounting frame 1. The mounting blocks 2 are cuboids in shape, and the welded joints undergo rigorous flaw detection to ensure welding quality. A connecting plate 3 is fixedly connected to the adjacent side of the two mounting blocks 2. The length of the connecting plate 3 matches the distance between the two mounting blocks 2. An adaptive mounting mechanism is fixedly connected to the outside of the connecting plate 3. An adjustment position mechanism is fixedly connected to the outside of the mounting frame 1. The structure includes an adjustment housing 14, which is manufactured by injection molding and has a cuboid shape. The exterior of the adjustment housing 14 is slidably connected to the interior of the mounting frame 1. The interior of the adjustment housing 14 is slidably connected to a limit plate 15. The function of the limit plate 15 is to limit the sliding range of other components inside the adjustment housing 14, ensuring the stability and accuracy of the adjustment process. Mounting brackets 16 are fixedly connected to the left and right sides of the exterior of the adjustment housing 14. The diameter of the connecting shaft 17 is designed according to the force of the rotating plate 20. The surface of the connecting shaft 17 is ground. The mounting bracket 16 is fixedly connected to the exterior of the connecting shaft 16, and the rotating plate 20 is rotatably connected to the exterior of the connecting shaft 17.

[0035] The rotating plate 20 is fan-shaped, and its central angle is designed according to the actual adjustment requirements. A positioning rod 21 is fixedly connected to the outside of the rotating plate 20. The end of the positioning rod 21 is designed as a wedge structure, which is convenient to be inserted into the slot 22 opened on the outside of the mounting frame 1 to realize the positioning and clamping functions. A telescopic rod 18 is fixedly connected to the outside of the rotating plate 20. An installation spring 19 is sleeved on the outside of the telescopic rod 18. Multiple slots 22 are opened on the outside of the mounting frame 1. The outside of the positioning rod 21 is clamped to the inside of the slot 22. When it is necessary to adjust the position of the adjustment mechanism, the elastic force of the installation spring 19 is overcome, and the rotating plate 20 is rotated. The positioning rod 21 is disengaged from the slot 22. After the adjustment is in place, the installation spring 19 releases its elastic potential energy, pushes the rotating plate 20 to rotate, and makes the positioning rod 21 re-clamp in the corresponding slot 22.

[0036] The adaptive mounting mechanism includes a mounting housing 4, which is the basic structure of the adaptive mounting mechanism. It has good insulation, impact resistance and chemical corrosion resistance, and can adapt to the complex electrical environment inside the distribution cabinet. The external of the mounting housing 4 is fixedly connected to the outside of the connecting plate 3. The internal of the mounting housing 4 is fixedly connected to a return spring 5. One end of the spring is welded into the bottom slot 22 inside the mounting housing 4. The size of the slot 22 matches the outer diameter of the spring to ensure stable installation of the spring. The external of the mounting housing 4 is slidably connected to a pressing rod 6, which is machined by a CNC machining center to meet the needs of installation and adjustment. The external of the pressing rod 6 is fixedly connected to a mounting clamping plate 13.

[0037] It can increase the friction with the drawer-type functional unit to ensure the clamping effect. The upper and lower ends of the external pressing rod 6 are fixedly connected to the connecting frame 7. The rotation angle range of the rotating plate 8 on the connecting frame 7 is precisely controlled by the limiting device. The external connecting frame 7 is rotatably connected to the rotating plate 8. The size of the rotating plate 8 is designed according to the installation requirements of the damping block 10. The external rotating plate 8 is rotatably connected to the connecting frame 9. Its surface is specially treated and has a certain roughness to increase the friction with the internal mounting surface of the distribution cabinet. The internal design of the damping block 10 has a special structure that can automatically adjust the magnitude of the damping force according to the movement speed and direction of the pressing rod 6 to ensure the stability of the adaptive installation process. The bottom of the connecting frame 9 is fixedly connected to the damping block 10. The external connecting plate 3 is fixedly connected to the reset assembly. The reset assembly includes a fixing rod 11. The external fixing rod 11 is fixedly connected to the external connecting plate 3. The external fixing rod 11 is sleeved with a tension spring 12.

[0038] Reference Figures 3 to 5The outer surface of the rotating plate 8 contacts the outer surface of the mounting clamp 13, and the outer surface of the mounting clamp 13 contacts the outer surface of the mounting housing 4. The end faces of the mounting clamp 13 and the mounting housing 4 that are in contact are ground to ensure the sealing and stability when they are in contact. One end of the tension spring 12 is fixedly connected to the inside of the connecting plate 3, and the other end of the tension spring 12 is fixedly connected to the outside of the damping block 10. The damping block 10 is made of high-damping rubber and stainless steel plate, and has a U-shaped groove 22 on the outside. The width is adapted to the size of the hook. By embedding and injecting high-strength structural adhesive, the tension spring 12 is ensured to be firmly connected and not fall off during the stretching and reset process.

[0039] Working principle: When installing electronic components, the electronic components are clamped to the mounting clamp 13, which in turn compresses the mounting clamp 13. This compresses the compression rod 6, causing the rotating plate 8 outside the compression rod 6 to rotate. Under the action of the rotating plate 8, the damping block 10 slides outside the connecting plate 3 via the connecting frame 9. This allows the damping block 10 to compress the tension spring 12 outside the fixing rod 11, thereby fixing the electronic components to the mounting clamp 13. The compression rod 6 then compresses the return spring 5, thus improving the installation stability of the electronic components.

[0040] When adjusting the mounting frame 1, pressing the rotating plate 20 causes it to press against the mounting spring 19 on the outside of the telescopic rod 18. This causes the rotating plate 20 to separate from the slot 22 on the outside of the mounting frame 1 via the positioning rod 21, allowing the mounting frame 1 to slide inside the adjusting housing 14. When the mounting frame 1 is adjusted to the appropriate position, releasing the rotating plate 20 causes the mounting spring 19 to rebound, causing the rotating plate 20 to separate from the slot 22 via the positioning rod 21, thus achieving the adjustment of the mounting frame 1.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
